Specification of Letters Patent. Patented J an. '7, 1919.

Application filed June 22, 1917. Serial No. 176,341.

To all whom it may concern:

Be it known thatl, EDWARD A. WILLIAMS, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Device for Lowering VVindow-Sash; and I do hereby declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in the art to which it appertains to make and use the same.

The invention is a device for lowering the upper sash of a window and seeks to provide, as one of its Objects a means for lowering such upper sash without the necessity of having to raise the lower sash to accomplish this.

Another object of the invention is to provide a cheap and eflicient device designed for easily attaching to the window frame and having means connected with the sash, whereby the latter may be lowered or raised witllliout having to interfere with the lower sas Other objects of the invention will appear from the detailed description which follows.

Two specific embodiments of the device are set forth in the accompanying drawings but to neither of these is the invention to be restricted. Reduction to practice may sug gest certain changes or alterations and these the right is claimed to make, provided they be not incompatible with the spirit of the appended claim.

The same numerals of reference designate the same parts in all thefigures of the drawings, wherein:

Figure 1 is a view of a portion of the window frame showing the invention attached.

Fig. 2 is a view showing the window frame and sash in section, showingthe device in edge elevation.

Fig. 3 is a detailed perspective view of a portion of the sliding arm.

In the drawings, l'represents a window frame having the upper sash 2 and the lower sash 3.

' The device for raising and lowering the upper sash is contained on the side of the window frame, so that it may not obstruct the light from the window or appear unsightly from the outside. This embodiment comprises an eye 12 fixed in the top of the sash 2 at its center. An arm 13 engages this eye, the arm terminating in an integral sleeve 14 which is adapted to slide over the rod 10. The rod 10 has an angled end through which protrudes a foot 15 by means of which the upper end of the rod is secured to the frame 1 with the aid of the screws 16..

At the bottom ofthe rod 10 a bracket 17 is attached to the frame 1 by means of the screw 18. This bracket has an eye through which the rod 10 passes and in which it is secured by means of a set screw 19.

Where the rod 10 blends into its angled end 11, a grooved roller 20 is rotatively mounted, the roller being supported on the screw stud 21. An endless cord 22 passes 13, the stems 24'project. These stems have the forked end 25 in which the rollers 26 are rotatively mounted, these rollers being designed to bear upon the frame 1 and to prevent the sleeve 14. from binding on the rod 10 as it is drawn up and down the latter and offsetting the tendency of the pull of the sash 2 on the arm 13 to create this binding effect of the sleeve 14 on the rod 10.

It will be seen that by pulling on one side of the cord 22 the sleeve 14: is moved down the rod 10, carrying with itthe arm 13 and lowering the sash 2 to which the arm 13 is connected. The -pulley on the other side of the cord 22 reverses this operation and of course raises the sash 2.

In applying the embodiment shown in Fig. 3, it is essential that the eye 12 be in the center of the sash, so that the pull thereon will be in the center. The device is capable of attachment to windows of various widths, because of the fact that the eye 12 and arm 13 are not rigidly connected to. gether. The eye 12 can always be placed in the center of the sash and the arm made to engage it by placing the end of the arm in the eye, the distance which the arm will pro ject beyond the eye being determined by the width of the window to which the device is applied.

The screw eyes or any other acceptable means permitting a cord to be drawn through them may be used in place of the rollers shown and wire ropes or chains may be used in place of the cord shown without departing from the Spirit of the appended claim.

What is claimed is:

In a device as set forth, the combination with'an upper window sash mounted in a window frame, of an eye on the front face of the upper rail of the sash substantially midway between the end of said rail, a pair of brackets secured to the inner'part of one side of the frame, one above the other, a guide rod mounted in said brackets, abracket arm disposed horizontally in parallelism with the face of said upper sash and having a cylindrical part loosely engaging through said eye, said bracket arm extending in a direction from the eye toward the side of the window frame and provided with a depending laterally extending portion terminating in an elongated sleeve, through whichfthe guide rod vertically engages,'said sleeve owing to the depending portion being below and to one side of the horizontal part Copies of this patent may be obtained for of the bracket arm, a pulley mounted on the upper bracket, a loop cord passing over the :3?

and engaging the inner face of the window u frame, to assist in guiding the sleeve and preventing angular binding of the sleeve on the guide rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD AUSTIN WILLIAMS.
